[英]Ag-Grid ASSERTION ERROR: Type passed in is not ComponentType, it does not have 'ɵcmp' property
[英]ASSERTION ERROR: Type passed in is not ComponentType, it does not have 'ɵcmp' property
每当应用程序运行时我都会收到此错误,但不会导致我在当前开发中出现问题(我认为)我想了解此错误并知道它来自哪里,因为我完全迷路了,我什至无法发布相关信息代码。 但我会尝试..
所以这些是主要路线(appModule):
const routes: Routes = [
{path:'home', component:HomeComponent, canActivate:[AuthGuardService]},
{path:'detail/:id', component:DetailComponent},
{path: 'register', component: RegisterComponent},
{path:'login', component: LoginComponent},
{path:'', redirectTo:'login', pathMatch: 'full'},
{path:'**', redirectTo:'login'}
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
我有一个核心模块,所有组件都已注册,我正在导入RouterModule.forChild([])
:
@NgModule({
declarations: [HomeComponent, DetailComponent, RegisterComponent, LoginComponent],
imports: [
CommonModule,
FormsModule,
ReactiveFormsModule,
RouterModule.forChild([])
]
})
export class CoreModule { }
package.json:
{

"scripts": {

编辑应用模块
@NgModule({
declarations: [
AppComponent,
],
imports: [
BrowserModule,
HttpClientModule,
BrowserAnimationsModule,
CoreModule,
NgbModule
],
providers: [DataService, fakeBackendProvider, AuthService, AuthGuardService, ShoppingCartService ],
bootstrap: [AppComponent, HttpClient]
我从未见过此错误。它是 Angular 9 问题吗? 难道我做错了什么?
此错误可能是由于两个常见错误
当您加载模块而不是组件时,反之亦然,则会出现此错误。
{
path: 'login',
component: LoginModule // mistake
}
{
path: 'login',
loadChildren: () => import('./login.module').then(m => m.LoginComponent) // mistake
}
您的应用程序模块的引导数组中有 HttpClient 。 这就是它给出这个错误的原因。
我有同样的错误,发生在我使用matDialog.open()
需要一个组件而不是一个模块的方法时。
请务必导入您正在使用的组件
main.module.ts
import { YourModalModule } from './your-modal.module.ts'// <-- .module.ts
//...
@NgModule({
imports: [
YourModalModule
]
})
main.component.ts
import { YourModalModule } from './your-modal.component.ts' // <-- .component.ts
//...
const confirmDialogRef = this._matDialog.open(YourModuleComponent, {})
// ...
编辑
在图书馆工作时也遇到了同样的错误。
导入的路径指向不正确的.umd
import { YourModuleComponent } from 'dist/website/bundles/my-lib.umd' // <-- mistake
const routes: Routes = [{ path: '', component: YourModuleComponent }]
import { YourModuleComponent } from './your-module.component' // <-- correct
const routes: Routes = [{ path: '', component: YourModuleComponent }]
当我不小心从页面的 Typescript 文件中的 @Component 装饰器中删除了 @ 字符时,我收到了这个错误。 例如:
@Component({
selector: 'app-reset-password',
templateUrl: './reset-password.page.html',
styleUrls: ['./reset-password.page.scss'],
})
export class ResetPasswordPage {}
当您打开matDialog并传递除组件之外的任何其他类型时,您也会收到此错误。
我将指令而不是组件传递给dialog.open
方法。
this.dialog.open(
MyDirective, //Make sure this is component
{...}
);
我只是遇到了同样的问题,但我的模块或组件文件及其导入没有任何问题。 我刚刚删除了 .angular 文件夹并再次运行 yarn run build 并且一切正常。
